One ERP for the office and one offline-first app for the field — so what happens at the tower today is on the project manager's screen today, not next week.

A crew finishes a tower installation in a stretch of country where the signal drops to nothing. The job is done — but the record of it isn't. The site notes go into a notebook, the material issue goes onto a loose sheet, the timesheet gets filled in from memory three days later back at the office. By the time it reaches the project manager, the numbers are soft, the billing is late, and nobody can say with confidence how much cable actually went into that span. Multiply that by hundreds of active sites and the operation is running on a picture of itself that is always several days old.
That was the daily reality at Posidon Infratel Solutions Pvt. Ltd., a telecom and engineering infrastructure company that has deployed over 1,400 mobile towers and laid more than 2,000 km of optical fibre. Growth had outpaced the reporting: field teams were still on manual methods, site-level inventory usage was invisible, and departmental data sat in fragments that never quite reconciled. Acube, an Official ERPNext Partner, put the whole operation on one ERPNext backbone and gave the field a purpose-built Flutter app that works with no network at all.
The headline result: a 75% reduction in reporting delays between field and office, 30% better operational efficiency, and 50% more accurate inventory tracking.

work was finished long before it was recorded.
material consumed at a site was a guess until much later.
projects, HR, stores and accounts each held a partial truth.
invoices waited on paperwork that was still in a vehicle somewhere.
the exact places the work happens are the places an online-only system fails. > The cost of staying as-is: on infrastructure rollouts, late data is expensive data. Unbilled work ages, material shrinkage hides in the gap between issue and report, and project managers make today's decisions on last week's picture.
A single ERPNext platform for head office, paired with a dedicated mobile application built for people standing at a tower base with one bar of signal — designed around the deployment workflow first, then configured to fit.
| Capability | What it gives you |
|---|---|
| ERPNext customisation — Projects, HR, Inventory, Timesheets | Core modules reshaped around telecom deployment workflows, so the system matches how a rollout actually runs instead of forcing the rollout to match the system. |
| Flutter-based field app | Engineers log tasks, record material usage, capture site photos and enter timesheets from the phone in their hand — no paper, no re-keying at the office. |
| Offline-first capture | The app works with no connectivity at all. Work gets recorded where and when it happens, not hours later from memory. |
| Real-time synchronisation | Data syncs automatically between devices and the ERPNext backend the moment connectivity returns — nothing is queued in someone's head. |
| Geo-tagging & site reporting | GPS-enabled traceability of field activity, so every entry is anchored to a real place and time. |
| Approval workflows & role-based dashboards | Managers verify entries, monitor progress and manage deployments from live dashboards scoped to their role. |
| Structured training & change management | Onboarding for both field and office personnel, so adoption was designed in rather than hoped for. |
The gap between doing the work and knowing about the work effectively closed.
| Outcome | Impact |
|---|---|
| Field-to-office reporting delays | 75% reduction |
| Overall operational efficiency | 30% improvement |
| Inventory tracking accuracy | 50% increase |
| Traceability | Real-time, GPS-enabled visibility of field activities |
| Future readiness | A scalable ERP backbone for expansion into Smart City, IoT and 5G infrastructure projects |
Timesheets, material consumption and task progress now arrive from the site itself. Project managers work from live data, billing follows completed work instead of chasing it, and site-level inventory is something the business can see rather than reconstruct.
We mapped Posidon's deployment workflow before configuring anything, then customised ERPNext's Projects, HR, Inventory and Timesheet modules to that reality — which is exactly why the system stuck.
An offline-first app is the difference between a field tool people use and a field tool people abandon at the first dead zone.
Structured training for both field engineers and office staff, because a system nobody enters data into is just an expensive database.
Ongoing support keeps the platform accurate and evolving as the project mix grows.

Yes. At Posidon Infratel we ran tower and fibre deployments through customised Projects, Inventory, HR and Timesheet modules, with approvals and role-based dashboards on top. The workflow is shaped around how a rollout is actually executed, not a generic project template.
That was the core constraint here, and the app is offline-first because of it. Engineers log tasks, materials, photos and timesheets with no connectivity, and everything syncs to ERPNext automatically once a signal is available.
Field engineers record material consumption at the point of use, tied to the site and the project. That's what took inventory tracking accuracy up by 50% — the record is created where the material is issued, not reconstructed later at the office.
Yes. Field entries are geo-tagged, giving real-time, GPS-enabled traceability of activity. Managers approve entries through workflows rather than accepting them on trust.
They did at Posidon. We deliver structured onboarding and training for both field and office teams as part of the engagement, and we build the app around the way crews already work — one screen, minimal typing, works with no network.
That was a design goal. The ERP backbone was built to extend into Smart City, IoT and 5G infrastructure projects, so new project types plug into the same platform rather than needing a new one.
